Once upon a time there was a man who dropped a silver bowl into the sea while crossing it.
He pondered, "I'm going to make a mark on the water. I'm carrying on my journey now. But I'll come back for it later."
After two months' travel during which he visited Ceylon and many other countries. On seeing a river, he jumped into the water looking for the bowl he had lost before.
"What are you doing there?" people asked. He replied, "I have lost my bowl. Now I would like to get it back."
People went on, "Where did you lose it?" He answered, "I lost it crossing the sea."
Again people asked, "How long ago did you lose it?" He answered, "I lost it two months ago."
People asked, "Since you lost it two months ago in the sea, why are you looking for it here in the river?" He answered, "I made a mark on the water where I lost the bowl. This water looks the same as the other. There seems no difference. That's why I'm doing this."
People went on, "Though all waters are identical, the place that you have lost it is there. How can you find it here?" Everybody jeered at him.
